Crayford focuser with 1:10 microfocuser designed for mounting on refractors - the focuser is attached to the telescope tube with three screws, the diameter of the mount on the telescope side is 96 mm. The element is made very solidly, using CNC technology, providing excellent comfort and precision of work. The focuser sleeve moves on 4 special bearings and a roller, thanks to this solution the construction does not show any play. Inside the sleeve there are diaphragms that improve the image contrast. The range of the focuser is 80 mm. In the 2" and 1.25" mounts , a clamping ring is used to protect the eyepiece sleeve from scratching and to ensure a secure hold of the eyepiece.

The extractor has 2 large adjustment screws. The first one is used to completely block the extractor's operation, it can be useful when using the heaviest accessories or to protect against accidental change of focus. The second screw allows you to smoothly adjust the resistance of the extractor's operation. When completely loosened, you can use light accessories (small glasses) and the extractor then works extremely smoothly. When fully tightened, the extractor works with slightly greater resistance, however the guaranteed maximum load is then 2.7 kg.

The focuser is compatible with the following telescopes, among others:
• Celestron 102GT; Nextstar 102 SLT; NexStar 80 SLT; Omni XLT 102; Omni XLT 150 f/5
